accumulate function not registered
by rogerL
After upgrade to 6.1.0.CR1 rule compilation is generating a pluggable
accumulate function registration error.
Partial stack dump:
Caused by: java.lang.RuntimeException: Error while creating KieBase[Message
[id=1, level=ERROR,
path=com/s/c/manager/rules/campaign/priority/prioritize.drl, line=31,
column=0
text=Unknown accumulate function: 'topPriority' on rule 'Insert highest
priority campaign'. All accumulate functions must be registered before
building a resource.], Message [id=2, level=ERROR,
path=com/s/c/manager/rules/campaign/priority/prioritize.drl, line=31,
column=0
text=Rule Compilation error $tc cannot be resolved to a variable]]
The associated rule and accumulate import are:
import accumulate com.s.c.util.HighestPriorityCampaignAccumulateFunction
topPriority;
rule "Insert highest priority campaign"
when
not TopCampaign()
accumulate(TargetCampaigns($list : list, list.size >0), $tc :
topPriority( $list ) )
then
insert(new TopCampaign($tc));
end
Is this syntax no longer correct?

Comparing Objects of same class.
by naresh.t
HI Team,
We came in situation where we need to compare our objects of same class.
For example, we have a class like SampleData.java. It has fields like 1) No
2) Student Name 3) DOJ(date of join)
Now, we want to write a Rule to get the Student Details like
1) if any 5 students joined in 2 days of span
This rule might changed dynamically like for now it is 2 days but in future
it may be 1 day or 3 days etc.,
Please provide any suggestions on this...
Thanks & Regards
Naresh

Possible problem in PathMemory
by rjh
Hello,
I developed a system where dynamic salience for some particular rules
doesn't rules. However, it is very hard for me to create a simple test case
unless I publish the entire rule files. In the system, some rules using
dynamic salience work and some don't, but I don't know why.
I debugged into the drools-core source code, and found out the following
code in branch 6.0.x.
(https://github.com/droolsjbpm/drools/blob/6.0.x/drools-core/src/main/java...)
Line 98 - org.drools.core.reteoo.PathMemory::doLinkRule
int salience = ( rtn.getRule().getSalience() instanceof
MVELSalienceExpression)
? 0
: rtn.getRule().getSalience().getValue(null,
rtn.getRule(), wm);
Line 113 - org.drools.core.reteoo.PathMemory::doUnlinkRule
int salience = ( rtn.getRule().getSalience() instanceof
MVELSalienceExpression)
? 0
: rtn.getRule().getSalience().getValue(null,
rtn.getRule(), wm);
I wonder if this is a bug that put the first value and the second value
reversed. At least I fixed my problem after reversing them.
Thanks.
Jinghai

Noob question: graph searching, query, root node for a given node
by Borris
I'm after a quick bit of help on how to do something that I think should be
easy but I can't work out how.
I have a Java-side class that essentially is something like
declare Datum
description: String
broader: List <Datum>
narrower: List <Datum>
end
These are arranged in a graph. Root nodes have no items in their broader
list. I want a query that takes a datum and yields the root nodes for that
datum. I think this should look something like
query rootDatumsFor( Datum datum, Datum result )
not Datum() from $datum.broader
or
rootDatumsFor( $datum.broader, $result )
end
but I then get confused. When there are no broader items, I am unclear how
to assign $datum to $result. And I'm not convinced I'm doing the recursion
correctly either.
If an experienced Drools author could spend a minute and show me how to do
this sensibly, I would be very grateful.

Need help in understanding Data enumeration’s drop down list configuration
by Shrinath Managuli
Hi Drools,
Need help in understanding Data enumeration’s drop down list configuration,
I had created a simple data enumeration as,
[cid:image001.png@01CF8A37.D4053860]
For this, I also created a Customer object with a code field as String at org.kie.example.project1 package.
While creating guided rule, I’m unable to view the enumeration as drop down as like below,
[cid:image002.png@01CF8A37.D4053860]
I had tried this scenario with JBoss BRMS 6. Please help me to understand on how to populate the drop down using data enumeration.
Thanks,
srinath

NPE spring-boot project via a jar
by rogerL
Hi,
Running into NPE on application boot up. It appears to be related to a
previous topic. I didn't add to it as the last entry appears to veer off
topic and didn't want it lost in the wash.
http://drools.46999.n3.nabble.com/rules-users-NullPointerException-with-k...
Using kie-spring-6.1.0.Beta4.jar, spring 4. As per the former topic, the

Fuse ESB & Drools 6 - Fire-until-halt configuration using persistence
by Sergio Besada
Hi,
I have seen that in the drools version 6.1.0.Beta4, the command
fire-until-halt is developed using persistence but drools doesn't let me
test it because this command implement the interface
"UnpersistableCommand" so I have eliminated this interface and I have
tested this configuration.
Surprisingly, Drools works as I expected and doesn't throw any exception,
¿Where is the problem in this configuration?

Fusion, Insert Events with timestamp in the past.
by SebastianStehle
Hi,
I am working on an existing drools project. We have a lot of rules with
"after" or "not after" relationships.
One of the problems I run into is when updating the rules. At the moment a
new session will be created and all facts are inserted from the old to the
new session. But something does not work in the scenario. To reproduce the
problem I made a simple test with the following rule:
rule "not after"
when
$message : DroolsSimulationMessage(value == 1) not
(DroolsSimulationMessage(value == 2, this after [1s, 10s] $message))
then
end
I inserted an event with a timestamp 5 seconds in the past and I expect the
rule to be activated 5 seconds after the event was inserted. But in my
scenario it does not work, the rule is activated after 10 seconds. This is a
very important point to make the current update progress work. Should it
work and if not is there a better way to realize rule-updates?
Thanks you in advance,
Sebastian
